Abstract
Description
Technical Field
[0001] This utility model relates to the field of nonwoven fabric technology, specifically to a pre-treatment and shredding device for nonwoven fabric waste. Background Technology
[0002] In the production process of nonwoven fabric, some substandard nonwoven fabric products and some edge waste from cutting are generated. In order to avoid waste, these nonwoven fabric wastes are generally recycled. However, due to the large volume of the edge waste and substandard products from nonwoven fabric cutting, they occupy space when piled up. Therefore, they need to be crushed. However, during crushing and feeding, there are often phenomena such as entanglement and knotting between the waste materials, which will form blockages and pile up at the feed inlet, which is not conducive to crushing. If pre-treatment of the waste materials is required before crushing, traditional cutting blades may not be able to cut the waste pile due to insufficient blade sharpness or insufficient force. Therefore, this utility model proposes a pre-treatment and crushing device for nonwoven fabric waste. Utility Model Content

[0021] Please see Figures 1-2In this embodiment, a pre-treatment and shredding device for non-woven fabric waste is provided, including a machine frame 1. A waste bin 2 is disposed in the middle of the machine frame 1, and a cutting groove 21 is formed on the surface of the waste bin 2. A saw blade 7 is disposed in the cutting groove 21. A first linear drive mechanism 3 and a second linear drive mechanism 4 are respectively installed on the vertical inner walls on both sides of the machine frame 1. A reciprocating drive mechanism 5 is installed on the first linear drive mechanism 3, and a second slide block 8 is installed on the second linear drive mechanism 4. The reciprocating drive mechanism 5 includes a mounting plate 51, and a first slide block 6 is fixedly connected to one side of the mounting plate 51. The two ends of the saw blade 7 are slidably mounted on the first slide block 6 and the second slide block 8, respectively. The reciprocating drive mechanism 5 also includes a drive shaft 52 rotatably mounted on the mounting plate 51, and the drive shaft 52 is driven to rotate by a drive source. One end of the drive shaft 52 is fixedly connected to a first movable rod 53, and the end of the first movable rod 53 away from the drive shaft 52 is rotatably connected to a second movable rod 54. The end of the second movable rod 54 away from the first movable rod 53 is movably mounted on a first slide block 6. The drive source is a motor. A first slide groove 63 is provided on the first slide groove 63, and a first sliding member 61 is slidably mounted on the first slide groove 63. The second movable rod 54 is rotatably connected to the first sliding member 61. A second slide groove 81 is provided on the second slide block 81. The saw blade 7 is equipped with a second sliding member 82. One end of the saw blade 7 is fixedly connected to the second sliding member 82, and the other end of the saw blade 7 is fixedly connected to the first sliding member 61. The second sliding groove 81, the first sliding groove 63, and the saw blade 7 are all horizontally arranged, and an installation piece 62 is fixedly connected between the saw blade 7 and the first sliding member 61. Before the non-woven fabric waste needs to be crushed, it is first piled in the waste bin 2, and the saw blade 7 is used to perform pre-crushing treatment. Specifically, the first linear drive mechanism 3 and the second linear drive mechanism 4 are driven synchronously, which can synchronously drive the first slide 6 and the second slide 8 to move downward at the same frequency, thereby driving both ends of the saw blade 7 to move downward synchronously. The rotation of the drive shaft 52 of the reciprocating drive mechanism 5 can drive the first movable rod 53 and the second movable rod 54 to rotate. Under the limiting action of the first slide groove 63, the second movable rod 54 can drive the first sliding member 61 to move horizontally reciprocally within the first slide block 6. Since the first sliding member 61 is fixedly connected to the saw blade 7, it can also drive the saw blade 7 to maintain horizontal reciprocating movement while moving downward. Under the limiting support action of the second slide groove 81, the saw blade 7 and the second sliding member 82 can also be guaranteed to move downward and horizontally reciprocating synchronously, thereby achieving good shredding of non-woven fabric waste in the cutting groove 21.
[0022] In this embodiment, the first linear drive mechanism 3 includes a first threaded seat 31 slidably mounted on the equipment frame 1. A first threaded rod 32 is threadedly connected to the inner surface of the first threaded seat 31, and a first motor 33 is mounted on the first threaded rod 32 to drive its rotation. The second linear drive mechanism 4 includes a second threaded seat 41 slidably mounted on the equipment frame 1. A second threaded rod 42 is threadedly connected to the inner surface of the second threaded seat 41, and a second motor 43 is mounted on the second threaded rod 42 to drive its rotation. Both the first threaded seat 31 and the second threaded seat 41 are connected to the equipment frame 1 via sliding bars. The frame 1 is slidably connected, and the first threaded seat 31 and the second threaded seat 41 slide up and down along the vertical side wall of the equipment frame 1. The first motor 33 and the second motor 43 rotate at the same frequency, which can drive the first threaded seat 31 and the second threaded seat 41 to move downward at the same frequency, thereby completing the synchronous downward driving work. Of course, the first linear drive mechanism 3 and the second linear drive mechanism 4 can also be driven by hydraulic cylinders or electric cylinders. However, compared with hydraulic cylinders or electric cylinders, the drive structure with threaded seat and threaded rod has better stability during downward movement.
[0023] In this embodiment, the waste bin 2 is filled with non-woven fabric waste to be processed, and a conveying mechanism 22 is provided at the bottom of the non-woven fabric waste to be processed. The conveying mechanism 22 can be a conveyor belt or a sliding plate. The position of the non-woven fabric waste to be processed inside the waste bin 2 can be adjusted by manually pushing the sliding plate horizontally, so that the saw blade 7 can shred the non-woven fabric waste at different positions.
[0024] In summary, this utility model, by setting a waste bin 2 with a cutting groove 21 inside the equipment frame 1, and setting a saw blade 7 on the cutting groove 21 that is driven to move horizontally back and forth by a reciprocating drive mechanism 5, can realize the shredding of non-woven fabric waste in the waste bin 2. Compared with the traditional shredding process using a downward-pressing cutter, it has a better shredding effect on non-woven fabric waste, and is less likely to fail to cut due to insufficient force or insufficient blade sharpness, thereby improving the pretreatment effect of non-woven fabric waste and thus facilitating subsequent crushing and feeding.
